If we look at the statistics of the AC Milan vs Bologna match, of course the result is not like that, but AC Milan won with a score above 2 because AC Milan had 33 kicks during the match.
To keep the Serie A title, a draw against Bologna is not a good result but this result can create a great opportunity for Inter Milan to shift AC Milan in 1st place in the standings because of a difference of 1 point.
You're right Milan should watch out Inter if both teams get the same points then Inter more entitled to the title because they have more goals
Therefore there is no reason for Milan to draw in the upcoming match or Inter will mess them up in the table. I can see Inter more seriously after Inter beat Juventus yesterday this is an important point for them.
